The Chinese character written in a red color means Saki and was written by a local calligrapher Mitsuharu Nakajima. He wants Koimari brewery to step forward to the future (Saki means "forward" in Japanese). The upper label says a junmai-ginjo nama zake. Junmai-ginjo types are brewed using only rice which is highly polished (no liqueur is added during production). Nama zake is sake which is not heat-sterilized (sake is usually heat-sterilized twice after production).
Saki is slightly yellow but very clear. It has slightly apple-like aroma. It tastes sweet but has a very clean finish. Therefore, Saki is very easy to drink. I drank half of the bottle only in 10 minutes! Koimari brewery produces only a small amount of sake. Therefore, it is relatively difficult to get one but you can buy one at Shirouzu saketen in Kasuga City.
